Servers exposing check_image_tag
From the publisher:Does this image:tag exist, how big is it, and which platforms does it cover? Use this before writing a FROM line or a compose file. On a hit it returns size, platforms, arm64/amd64 support and the digest. On a miss it says whether the IMAGE exists but the tag is wrong, and lists real tags newest first so the caller can correct itself. Defaults to tag "latest" when none is given.
Install docker-facts →Parameter Type Description tagstring Tag to check, e.g. "20-alpine". Defaults to "latest". name*string Docker image name as you would write it in a FROM line: "node", "postgres", "grafana/grafana". Official images may omit the "library/" prefix.
